* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
* fsl-ddr: use the 1T timing as default configurationDave Liu2009-01-23-0/+3
| | | | | | | | | For light loaded system, we use the 1T timing to gain better memory performance, but for some heavily loaded system, you have to add the 2T timing options to board files. Signed-off-by: Dave Liu <daveliu@freescale.com> Acked-by: Andy Fleming <afleming@freescale.com>
* 85xx: Introduce CONFIG_SYS_PCI*_MEM_VIRT for FSL boardsKumar Gala2009-01-23-4/+4
| | | | | | | | | Introduce a new define to seperate out the virtual address that PCI memory is at from the physical address. In most situations these are mapped 1:1. However any code accessing the bus should use VIRT. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>
* 85xx: Use CONFIG_SYS_{PCI*,RIO*}_MEM_PHYS for physical address on FSL boardsKumar Gala2009-01-23-3/+3
| | | | | | | | Use the _MEM_PHYS defines instead of _MEM_BUS for LAW and real address fields of TLBs. This is what we should have always been using from the start. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>
* 85xx: Convert CONFIG_SYS_{PCI*,RIO*}_MEM_BASE to _MEM_BUS for FSL boardsKumar Gala2009-01-23-3/+3
| | | | | | | | Use CONFIG_SYS_{PCI,RIO}_MEM_BUS for the bus relative address instead of _MEM_BASE so we are more explicit. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>
* mpc8xxx: LCRR[CLKDIV] is sometimes five bitsTrent Piepho2008-12-19-1/+1
| | | | | | | | | | | | | | On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits instead of four. In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems. It should be safe as the fifth bit was defined as reserved and set to 0. Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

* Pass dimm parameters to populate populate controller optionsHaiying Wang2008-10-18-1/+4
| | | | | | | | | | | | | Because some dimm parameters like n_ranks needs to be used with the board frequency to choose the board parameters like clk_adjust etc. in the board_specific_paramesters table of the board ddr file, we need to pass the dimm parameters to the board file. * move ddr dimm parameters header file from /cpu to /include directory. * add ddr dimm parameters to populate board specific options. * Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.

* mpc85xx: workaround old binutils bugKumar Gala2008-08-10-5/+11
| | | | | | | | | | | | | The recent change to move the .bss outside of the image gives older binutils (ld from eldk4.1/binutils-2.16) some headache: ppc_85xx-ld: u-boot: Not enough room for program headers (allocated 3, need 4) ppc_85xx-ld: final link failed: Bad value We workaround it by being explicit about the program headers and not assigning the .bss to a program header.

* mpc85xx: Update linker scripts for Freescale boardsKumar Gala2008-07-31-21/+16
| | | | | | | | | | | | * Move to using absolute addressing always. Makes the scripts a bit more portable and common * Moved .bss after the end of the image. These allows us to have more room in the resulting binary image for code and data. * Removed .text object files that aren't really needed * Make sure _end is 4-byte aligned as the .bss init code expects this. (Its possible that the end of .bss isn't 4-byte aligned) Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* Big white-space cleanup.Wolfgang Denk2008-05-21-4/+4
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

| | | | | | | | | When we go to 36-bit physical addresses we need to keep the concept of the physical CCSRBAR address seperate from the virtual one. For the majority of boards CFG_CCSBAR_PHYS == CFG_CCSRBAR Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Remove erroneous or extra spd.h #includers.Jon Loeliger2008-03-05-4/+1
| | | | | | | | | | Many of the spd.h #includers don't need it, and wanted to have spd_sdram() declared instead.

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-1/+1
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>
* Reworked FSL Book-E TLB macros to be more readableKumar Gala2008-01-09-80/+65
| | | | | | | | | | | The old macros made it difficult to know what WIMGE and perm bits were set for a TLB entry. Actually use the bit masks for these items since they are only a single bit. Also moved the macros into mmu.h out of e500.h since they aren't specific to e500. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
